In recent years,China's economy has been growing at medium and high speed.However,with the development of economy and the progress of society,environmental problems are becoming increasingly severe.For a long time,pursuing the rapid growth of GDP unilaterally and ignoring the protection of ecological resources have greatly damaged the environment.In addition,the large population,the low level of the per capita natural resource possession and the low efficiency of high energy investment have not been improved,which also restricts the long-term development of China.Under these circumstances,the research and analysis of the sustainable development of the city is more urgent and necessary,and how to achieve the sustainable development of a region and evaluate the sustainable development ability of the city has become a common problem to be discussed by the scholars from all walks of life.The Yangtze River Delta Urban Agglomerations is a representative of China's advanced development.It is a concentrated reflection of China's whole development,and also a leader of China's continuous development towards the world.However,recently,in the process of economic and social rapid development in the region,there have also been some obstacles to the progress of city,including a large consumption of resources,intensification of air pollution and destruction of ecological balance.In the environment of increasingly ecological problems,the sustainable development research of the Yangtze River Delta Urban Agglomerations is more urgent and valuable.The main contents of this research are as follows: Firstly,the background of sustainable development and the importance of our country are explained in detail in this thesis.It also introduces the important status of the Yangtze River Delta Urban Agglomerations and its current development background,and explains the purpose and significance of this research.Through analyzing and drawing lessons from previous researches on sustainable development ability at home and abroad,finding out the breakthrough point of this thesis from the research methods.At the same time,the different definitions of sustainable development ability from different academic schools and the main factors that affect sustainable development ability are given by combining with literature reading and actual development.Secondly,the development status of the Yangtze River Delta Urban Agglomerations is analyzed in detail from the aspects of economic,social and resource environment,in order to understand the overall development of the region,so as to pave the way for the next research.Thirdly,the evaluation index system of sustainable development ability is established by drawing on the previous research experience on scientific selection evaluation index and considering the actual situation of the Yangtze River Delta Urban Agglomerations.The traditional DEA method and the modified DEA method are used to evaluatethe sustainable development ability of the Yangtze River Delta Urban Agglomerations,and the results of the two are compared.It is found that the modified DEA method is better than the traditional DEA method.Finally,according to the above research results,the scientific suggestions are put forward for the sustainable development of different cities in the Yangtze River Delta Urban Agglomerations,which will be of certain guiding significance for the more scientific and rational development of the region in the future.The results of this research are as follows:(1)By comparing the modified DEA with the traditional DEA method,the conclusion that the analysis method combined with the canonical correlation analysis and the DEA is more scientific and the result is more reasonable,which provides a new idea for the city performance evaluation.(2)The situation of sustainable development among in the Yangtze River Delta Urban Agglomerations is not balanced.As a whole,the sustainable development ability of Shanghai and Changzhou is strong,while the sustainable development ability of other cities in Jiangsu and Anhui is relatively low.(3)In cities with low sustainable development ability,there are two aspects,including technology and scale.Compared with the 2014,the Yangtze River Delta Urban Agglomerations' pure technical efficiency has been improved,and the overall sustainable development ability is increasing in 2015.There are different reasons of low efficiency in various regions: Jiangsu is mainly due to scale of production,while in Anhui,there are problems of both redundant input and scale of production.(4)In view of the shortcomings of the sustainable development ability in the Yangtze River Delta Urban Agglomerations,the corresponding suggestions are also put forward: in the future development process,on the one hand,the technological innovation should be pay more attention,and increasing the promotion of production technology.On the other hand,the production scale should be appropriately adjusted according to the actual conditions of different region,and improving the utilization rate of resources.
